Introducing PWM function: ARCTIC F PWM cooling fans, thanks to the innovative patented PWM Sharing Technology (PST), can share up to 5 fans (including CPU fans). The speed of the fans in this PST system is centrally controlled by a single PWM signal via BIOS.

With the increased load of all the cooling fans connected in the PST system will receive the signal from the BIOS to increase performance by increasing airflow and cool the system. At low loads vice versa Will-fans have less power and thus noise.

In conclusion, the advantages of the PST are:

(1) Speed ​​control individual fans with only one PWM signal from the motherboard (2) Ventilation can be achieved in a calm and efficient manner. Other cooling fans run slower at low load, which provides sufficient cooling at a much quieter operation than before. (3) Improved energy saving as cooling fans are not always at full load
